Apple: “Mojave is the last macOS release to support 32-bit apps”
Apple announced that the upcoming macOS Mojave will be the last version to support 32-bit applications. After the WWDC 2018 opening speech ended, Apple announced this information to the developer. With the launch of the OS X Leopard version in 2007, Apple introduced 64-bit applications for the first time, and the macOS High Sierra version launched last year has issued a warrant for 32-bit applications.

In April of this year, when the user opened the 32-bit application in the macOS 10.13.4 version, he would send a reminder to the user to warn them that the application needs to be updated and the application developer needs to optimize it. At present, Apple does not specify the restrictions that Mojave will impose on running 32-bit applications, but it can be confirmed that next year’s macOS will completely stop supporting.
With Apple’s official abandonment of support for 32-bit applications, 32-bit related frameworks will also be removed, including the QuickTime framework, Java 1.6 Apple framework, and Carbon HLTB.
